TypeError: to_excel () got multiple values ​​for argument 'sheet_name'

I am trying to store different data across different sheets like this:

import pandas as pd
from pandas import ExcelWriter
import xlsxwriter

// code
bio         = BytesIO()
with pd.ExcelWriter(bio, engine='xlsxwriter') as writer:
    dfStats.to_excel(writer, sheet_name='Summary')
    dfStockdata.to_excel(writer, sheet_name='HistoricalISIN')

# create the workbook
writer.save() // tried both with and without this line
bio.seek(0)
workbook    = bio.read()
excelFile   = workbook

However, I am getting the following error:

TypeError: to_excel() got multiple values for argument 'sheet_name'

How can I solve this?

You may try:



writer = pd.ExcelWriter('output//out.xlsx', engine='xlsxwriter')
dfStats.to_excel(writer, sheet_name='Summary')
dfStockdata.to_excel(writer, sheet_name='HistoricalISIN')
writer.save()

I tested several sampled data and it worked as expected:

import pandas as pd
from io import BytesIO

bio = BytesIO()

df1 = pd.DataFrame({'Data': [11, 12, 13, 14]})
df2 = pd.DataFrame({'Data': [21, 22, 23, 24]})

with pd.ExcelWriter(bio, engine='xlsxwriter') as writer:
    df1.to_excel(writer, sheet_name='Summary')
    df2.to_excel(writer, sheet_name='HistoricalISIN')

with open('pandas_file.xlsx', 'wb') as w:
    w.write(bio.getvalue())

Output:
